DropConstraintConstantAction

DropConstraintConstantAction(java.lang.String constraintName,
                            java.lang.String constraintSchemaName,
                            java.lang.String tableName,
                            UUID tableId,

                            int behavior,
                            int verifyType)

Make one of these puppies.

Parameters:

constraintName - Constraint name.

constraintSchemaName - the schema that constraint lives in.

tableName - Table name.

tableId - UUID of table.

tableSchemaName - the schema that table lives in.

indexAction - IndexConstantAction for constraint (if necessary)

behavior - the drop behavior (e.g. StatementType.DROP_CASCADE)

Method Detail
